Our invention consists in improvements in mechanism for acting upon aseries oit' elements such as the threads of a warp and is intended moreparticularly to provide means ior maintaining a Cooperative alinementbetween a progressively acting operating mechanism such for example asthe needle oit' a warp drawing machine and the individual members of twoor more separate groups of elements, which members are intendedsimultaneously to be acted upon by said operating mechanism. Such hy wayoi? illustration may be the threads o'l the warp, the series ot heddlesin the harness and the splits ot the reed in the warp drawing' machinereferred to.

Our invention is not'limited lin its ap'plication to any particularpurpose or to any particular machine 'or apparatus but by way ofillustration, in the accompanying drawings we have shown one form et thesame embodied ini a well-known type `of Warp drawing machine, manyfeatures of which are shown in patent to M. F. FieldNo. 755,861, datedMarch 29, 1904-.

In a warp drawing machine as ordinarily constructed, the warp threadsare-helddistended in a generally gparallel relation and adjacent to thewarp is arranged the harness and the reed in the same general relationwhich they are to occupy in the loom. lperating mechanism comprising aneedle or hoolrand appropriate driving mechanism uponv a moving carriageis given 4a progressive step by step movement erosswise 4the reed, the'harness and the warp, Iat each adance of the carriage the needle bei-ngcaused to move forward between the splits of the reed, through theeye ofthe-heddle to seize i one of the warp threads and draw the saidSpecification of Letters Patent.

thread back again through the heddle eye and the reed. The carriage thenadvances to permit a repetition of the same operation upon the nextadjoining thread. In the warp drawing machine as generally constructed,the step-by-step advance of the operating mechanism is designed withreference to the spacing of the heddles and, `ifi this be 'differentfrom the spacing of the warp threads or the reed splits, some correctiveor compensating movement of the warp threads or the reed or both withreference to the heddles becomes necessary. Ordinarily the total widthof the warp is materially greater' than the total width of the harness,and frequently the warp threads are irregularly spaced, in the one casecausing the warp threads to increasingly depart from correct alinementwith the operating mechanism, and in the other causing irregulardepartures from the proper alinement. y K

In the accompanying drawings we have shown one embodiment ot' yourinvention applied to a warp drawing machine, so that the individualmembers of the. heddles and the warp threads and the reed splits arebrought into cooperative alinement with the operating mechanism topermit the latter to act simultaneously upon the individual members oi'these three groups of elements, even though the latter tend normally tobe out ofalinement with each other,`

Our invention will be best understood by reference to the followingdescription, taken in connection with the accompanying drawings, whichshow, for illustrative purposes, one embodiment th ereof; while itsscope will be more particularly pointed out in the appended claims.

In the drawings we have shown a warp drawing machine of the general typeillustrated in patent to M. F. Field No. 755,861. The general -functionof this machine is to support the warp, the harness and the reed in thegeneral relation which they will sub sequently occupy in the loom andthere to permit appropriate mechanism to draw the individual threads etthe warp through the appropriate heddle or' the harness and be tween thesplits of the reed preparatory to placing these several elements withthe drawn warp in the loom.

For a description ot the details ol' the operation ot this machinereference may be had to the above-mentioned patent, it being suilicientfor the purposes ot our invention here to point out only the generaloperation thereof. The harnesses, oi which herein there are two,-a frontset (t and a rear set a, and the reed b are suitably supportedtransverse to the line of action of the drawing-in needle c, whichlatter is mounted for reciprocative movement, together with the needleoperating mechanism upon the trav cling carriage ci. The latter ismounted to travel through a step-by-step movement upon suitable wayslengthwise the frame oif the machine and parallel with the reed andharness, the mechanism for reciprocating the needle and advancing thecarriage at appropriate times being actuated from drivnig shaft d movingwith the carriage and receiving its movement from some suitable source(not shown). `When the needle is ready for its 'forward movement uponthe carriage, the arm ii is caused to move forward to separate thesplits ot the reed at the appropriate point so that the needle may withcertainty pass through the desired space therein. As in the prior patentreierred to the reed is supported somewhat loosely upon bearings b2permitting .it to yield or slide longitudinally so that it the splitsare irregularly spaced or Vfor any reason out ol alinement withreference to the hed-illes the reed frame will be ven a slightlongitudinal movement by the arm Z/ which has an approliriately shapednose, to bringl the same with certaii'ity into coi-rect alinement forthe action of the operating mechanism.

Suitable harness spreading and separating mechanism c2, fully disclosedin the sai d prior patent, advancing with the carriage and bearing adefinite relation thereto, is

caused intermittently to act upon the successive heddles of the harnessso that the appropriate heddle eye through which the warp thread is tobe drawn is separated in turn from the others and held within the pathof the advancing needle.

Then the needle advances it passes between the separated and properlyalined reed splits, and through the appropriate heddle eye, which latteris maintained by the separating mechanism in certain alinement withreference to the needle path. Further advancing the needle is caused topartially turn and seize a warp thread the latter be ing shown withreference to the reed and the harness eyes at c (Fig. l). The needle isthen immediately retracted drawing the thread through the heddle eye andbetween the splits of the reed, the thread being disengaged trom theneedle by a transverse movement of the knock-off linger d2. The needlehaving been fully retracted, the carriage is advanced another step, thearm 1) moved into the next adjacent space between the reed splits andthe harness separating mechanism turned to maintain the next successiveheddle eye in the advanced path of the needle. The operation is thenrepeated and again repeated untilthe entire warp has been drawn throughthe harness and thc reed.

The warp threads pass upward from the warp beam r (not shown) through a.gripping member or bar c (Figs. l and 5) over a shaft c2 which carriesmeans for irst stretching and then separating the threads, and to asecond gripping member or bar c3. The gripping member c3 clasps thethreads with a relatively slight friction but the gripping` n uab-er cwith a relatively greater friction, so that as the threads are seizedand drawn by the needle the loose ends thereof pass readily from thegripping member c3 but remain firmly held in the gripping member c. Theaction of the machine so lar described and the general construction andarrangement ol parts is substantially that ot lthe well known warpdrawing machine a type olt which is disclosed in the prior patentreferred to.

rlhe warp separating device c4 herein comprises spreading and separatingmeans carried upon the shaft c2, the latter being liournaled in hangerscarried by the standards d3 secured to and travelingr with the carriage(Lione of the said standards being shown in Figs. l, 3 and 5.

The separating mechanism is therefore caused to advance with thecarriage and act upon the successive threads of thewarp, sai d shaft c2vbeing given an intermittent rotation in a well known way by gearingdriven from the carriage. Referring to 5, the action of the Warpseparating device will be readily understood. The shaft e2 toward itsactive end is of increasing diameter and, as it advances beneath thethreads of the warp, gradually increases the tension thereupon, suitablecorrugations G5 being proA lGO vided .to stroke the threads intoparallel position. As the carriage and shaft c2 advance the successivewarp lthreads engage the lip of the warp separating feed screw portion cand are selected and separated one at a time and advanced by theintermittent rotation ofthe screw until-they reach the final position ofthe warp thread c. The separating screw having a fixed relation withreference to the carriage and therefore to the path ofthe needle thefinalposition as-A sumed bythe thread may be and is made to lie withcertainty within the needle path.

It will be seen that where the width of the warp is greater than thewidth of the series of heddles in eachxharness, the successive warpthreads will depart more and more from a position of alinement with thecorresponding heddles and from alinement with the needle which latter.advances at each operation just enough to pass through the nextseparated heddle eye. Although the warp threadseparating screw willotendto bring the warp threads into a position of alinernent with the needleyet if the warp is unmoved its threads become more remote with referenceto the. feeding screwitself as the operation proceeds. It is found tobe' important for the effective action ofv the separating ldevice thatthe warp threads should meet the screw e at an angle which. approximatesthe pitch of the screw thread7 but if the warp threads are fixed inposition this angle will continually decrease and will soon become toolittle to permit separation of the thread by: the screw.

In order to provide a corrective movement to correct the changingrelation between the operating mechanism and the warp threads, the warpbeam and the gripping bars e and e3 are mounted upon a frame orcarriage, which can be moved. lengthwise the machine to provide thenecessary compensating movement forthe warp.

Referring to Figs. 3 and 4, wherein the construction of one end of thisframe -or carriage is partially shown, thelatter consists of the two endsupports c7 which are hung upon. the horizontal rods es, the` latteradapted to move lengthwise over the horizontal grooved ,guiding rollersc". The clamp bar c is secured directly to the end piece c7, while the.clamp bar c3 is adj ustably pivoted upon the rod 610, the latter beingsecured to the said end piece e?. The opposite end of the carriage issimilarly constru cted. The` compensating adjustment of the warpcarriage may be manually effected through the rotatable rod (Figs. Sand4) the latter being geared by the beveled gears f to thetvertical shaftf2, the lower end of the said shaft f2 having secured thereon the pulleyf3. An endless band fx `embraces the pulley f3 and a correspondingV*pulley (see Fig. 2).-at the oppositeend of the machine,

ably but` rigidly secured (Fig. 6) as'by means of the pinsy f7 to rotatewith the pinion f6, the teeth. of the said pinion being in-engagementwith the rack 1- (FigA 2) secured to and movable with the warp carriage.If now the roll or. rod f is turnedV by hand the vertical shaftA f2 andpulley f3 is also turned, and movement of the'band fX effected. .Thisturns the pinion f6, and causes the longitudinally 'movable warpcarriage ylaterally to advance or recede relatively to the pinion andtherefore to the operating carriage d which carries the pinion; Thus, inthe machine illustrated the positionlof the warp may be adjusted fromtime to time by hand to compensate either for irregularities in thespacing of the warp threads or to offset the continually advancingposition-which the said warp threads bear to the operating mechanism asthe drawing-in operation proceeds.

rFor greater efficiency however, this corrective movement vshould beautomatic and regulated by the progress of the drawing-in operation andin the machine illustrated we have provided means which act-automati-'cally to move the warp, such means being thrown into and out ofoperation by the charging position of a feeler finger, the latter beingcontrolled by the position of the warp threads relatively to theoperating mechanism. This is accomplished in the following manner: Theshaft goto which is keyed the` band wheel f5 passes downward beneath itssupporting frame and is rigidly secured to the ratchet wheel g', wherebya turning of the latter will cause the corresponding movement of thepinion f6 and a compensating movement ofthe warp car-- ringe. vThe turnof the ratchet wheel is effected by a pawl L (Fig. l), pivoted upon therecilnocating pawl actuating rod h', the latter being connected to theoscillatingr link h2, the latter moved by the rod h3, connected to theneedle actuating lever h4. The connection is such that when the needleis moved inwardly the pawl actuating rod is also moved inwardly andcarries the pawl idly over the teeth of the ratchet wheel. When theneedle is retracted the pawl actuating rod is also retracted, and if thepawl is permitted to engage with the teeth of the ratchet wheel iteffects a slightmovement of the ratchet wheel and therefore of the kwarpcarriage,as described. The compensating movement' of the Warp carriageis therefore effected as it should be while the needle is in itsretracted position.

The means which automatically .control iis y the operation of this warpcompensating mechanism, is as follows. Swingingly mounted upon the armZ4 of the mechanism carriage, is the feeler finger z', having a properlyshaped nose z" correctly positioned to underlie the foremost of the warpthreads provided the latter are in the correct or the desired alinementwith reference to the separating screw c4 or other elements of theoperating mechanism. In Figs. 4 and 5 the warp threads are illustratedas having the desired relation to the separating screw, and the nose '11of the swinging .finger is held downward against the under side of theforemost warp threads, causing its opposite and angularly turned end 2to bear against the heel of the pawl lifting lever le, which isfulcrumed upon the pawl actuating rod 71,. rlhe lever is provided with apawl lifting linger 7c', which has an inturned end engaging a curvedslot 71,5 in the pawl, the proportions of these several parts being suchthat' when the nose of Vthe feeler is held downward by contact with thewarp threads, the lifting` lever K is forced backward and the pawlmaintained out of engagement with the teeth of the ratchet wheel g', thereciprocations of the pawl actuating rod being ineffective to causemovement of the warp carriage.

As the drawing-in operation proceeds, the warp threads will becomefarther advanced relativ dy to the needle and the nose of 'the feelerfinger and their angle of inclination to the separating screw less, sothat finally the witlnlrawal of the foremost warp tin-earl will free thefeelcr and the advance of the operating` carriage will be insuliicientto bring its nose under the next succeeding warp thread. rllhe 'ngerwill then move to the position shown in Fig. l, permitting' the liftinglever /c to swing forward and drop the pawl into engagement with theteeth of the ratchet wheel. The weights of the parts can be so adjustedas to permit the nose of the `teeler linger to press upward against thewarp threads with any desired tension, but preferably they areproportioned to permit the pawl slightly to overbalance the linger sothat the upward tendency of the latter is elatively slight and slightvariations in the tension of the warp threads will not affect theoperation of the device. llVhen the feeler linger mores to the positionshown in Fig. l, each reciprocation of the pawl mores the warp carriageslightly from right to left,r as viewed in Fig. o, and this compensatingmovement will continue by repeated slight increments until the desiredalinement of the warp in the separating mechanism is obtained. Eachretraction of the pawl operating rod 71, is accompanied by rearwardmovement of the lifting linger 7c, and the inturned end of the feelerlinger, so that the nose z" of the latter moves from a position abovethe plane of the warp threads on advancement of the pawl to a positionbelow the plane of the same on retraction of the pawl. if the correctivemovement occasioned by the retraction of the pawl is suliicient to bringthe next warp thread within the path of movement of the feeler fingernose, movement of the latter is arrested on the advancing of the pawland the latter is again withdrawn from engagement with the teeth of theratchet wheel and into the position shown in Fig. 4. Thus it will beseen that the nose of the feeler linger being located in the place wherethe foremost warp thread ought to be for the best conditions ofoperation, if the foremost warp thread is not in its designed positionin contact with the feeler finger, the warp carriage will beautomatically adjusted through a step-hy-step compensating movement tobring the leading warp thread into the desired position.

ln the description of the machine, it has been assumed that the endlessband f has no effect upon the automatic feed of the warp carriage, andin fact this is the case in the machine illustrated, for, hy referenceto Fig. 6, it will be seen that the pitch circle of the band wheel f5 issubstantially equal to the pitch diameter of the pinion fl", so that asthe operating carriage moves the pinion and band wheel along, the formerwill roll idly upon the rack and the latter upon the endless band.. l

lf the total width of the warp is less tha the total width of theharness, instead of greater, as has hereinbefore been assumed, theresultant compensating warp feed must be in the opposite direction tothat described,

that is to say, as the drawing in operation" progresses, the position ofthe warp threads will lag behind that of the corresponding heddles andthe inclination between the warp threads and the separating mechanismwill become greater and greater. To correct this the warp should hemoved from left to right, as viewed from the rear in F ig. 5, instead ofin the opposite direction. In order that this may be effected hy thesame mechanism as has been described, we have provided means so that thestep-hystep movement of the operating carriage from left to right (asviewed from the rear in Fig. may be made to cause a step-by-stepmovement of the warp in the same direction but farther than is requiredVto compensate for the increase in pitch of the warp threads, theautomatic compensating feed when brought into action by the feelerlinger being then permitted. to move the warp carriage back again fromright to left by an increment which is sufficient always to insure thecorrect alinement of the warp threads.

To accomplish this, the band wheel f5 is removably mounted on the shaftg and may be replaced by one having a greater pitch diameteil than thatshown in Fig. G. lf'this is done, each step-by-step advance of theoperating carriage which carries the shaft Will cause a smaller angularmovement of the band Wheel than before, consequently the pinion f willroll idly upon the rack r to lesser extent and will cause the rack tomovefrom left to rightv and thus carry the Warp along in the directionof travel of the mechanism carriage. The amount of this movement'tvhi'chis dependent upon the size of the band Wheel f5 is preferably greater bya slightincrement than is necessary to properly adjust the warp and onthe nent retraction of the needle, if the movement of the Warp has beentoo great and the foremost thread thereof is not in proper alinement,the rise of the feeler `finger will throw in the automatic compensatingmovement for the Warp. Y

It is to be observed that in the specific embodiment of our inventionillustrated, the warp carriage is positively positioned relatively tothe mechanism carriage b the compensating motive mechanism, an that thismotive mechanism is at all times under the controlv of the delicatelyadjustable feeling means. The latter may, of course, be embodied in agreat variety of forms. The feeler iinger or member has a movementtransverse to or crosswise of or to and from the plane of the Warp,instead of in vor substantially in the plane thereof. It Will be evidentfrom the foregoing description and from the illustration, andparticularly F ig.,

5, that'the nose or operative portion of the feeler inger contacts witha plurality of the leading Warp'v threads. i This construction is ofimportance and is preferably employed by us. A feeler finger vibratingor moving in the plane of the Warp tends to roll the thread back fromthe point of action of the separating mechanism, and tends to roll themover one another. This action is eliminatedy or prevented when thefeeler linger Works across or transverselyL of or to and from the planeof the Warp'. It will also be observed, viewing Figs. 4 and 5,' that thefeeler is made operative uponthe thread at a point relatively remoteyfrom the point of action ofthe separating mechanism. This is o'fpractical importance, inasmuch as the operation and character of theWarp separating mechanism herein illustrated are not dependent yupon thecontrolling with absolute nicety of the slope of the threads to beseparated. The feeler finger therefore may advantageously be located ata kpoint relatively remote from the point of action of the Warpseparating mechanism. l3`urthermore, y the feeler finger need not kWorkso accurately y as if the thread next to be separated or picked ofi' hadto be located With great eX- actness by the action of the separatingmechanism. i

These principles and features of operation of the feeler iinger ormember may be employed, Within the scope of our invention, invarioustypes of Warp separating or selecting machines, and We are therefore notlimited to theL use thereof in connection with a mechanism of thedrawing in type. i

Obviously, the presence or absence of the, Warp threads might be made tocontrol this mechanism by either stopping or starting the movement ofthe feeler finger, or by acting upon the motive mechanism in any Way tothrow it in or out of operation at the desired times. A constructionlike the one shown, however, has the advantage of simplicity, delicate'adjustment and sensitiveness. The vibratory movement of the feeler andits connection to the reciprocating driving mechanism of the needle isadvantageous also, in that the control of the feeler finger over theoperative connections between the reciprocating mechanism and thecompensating mechanism is periodic and times the advance of the Warpcarriage relatively to the needle carriage exactly with the retractionsof the needle. A

It isto bef understood however,that it is shown of the construction and inthe connection describedl forillustrative purposes only and vis notl limited to the particulardetails or the special 100 use referred to herein, 'but on the contraryis susceptible of application to other uses which A will be apparent tothose skilled in the art, wide departures from the construction andarrangement disclosed, and of embodiment 105 in a variety of forms towhich reference here is unnecessary.
